Original application filed December 21, 1908, Serial No. 468,508. Divided and this application filed June 3, 1915. Serial No. 32,000.

To all whom it may concern:

lie it. known that I, An'rnun J. BALDWIN, a citizen of the United States, residing at New York city. New York, have invented a certain new and useful Improvement, in Single Strand {Wire Glass Machines, of which the following is a full. elear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the aeemnpanying drawings forming part of this specification.

This invention relates to new and useful improvements in single strand WliG glfiSS machines and the subject-nutter of th s application is a division of my application for single strand Wire "lass machine filed Dccember 21. i908, Serial No. 463,508.

By single strand I mean that instead of embedding 1!, wire mesh into the sheet, of

as has heretofore been largely practised, I propose to embed one or more single Strands of wire into the sheet of glass. said strands being so arranged with respect to each other that they are electrically insulated from each other. the ends of the wires preferably projecting beyond the sheet ofv gins) to al'ord means for electrically connecting said Wires together.

The single strand sheets of glass made by my impr ved machine are used for various purgmses, illllfillfl which may he mentioned windows and r;l( \li l1!s. the walls and partitions of elevator shafts, for dust. and wind guards of automobiles and other places where it desired to have single strands of wireembedded iuthe glass instead of the wire mesh as has heretofore been used. By r ason oi the t thut two or more of the strands, of wire in a. shoot of glass can be. elem. .caliy connected, said glass is also applicable for use in connection with vaults, juilrliixht. showwases or wherever an alarm bl wout is valuable and iieovssul vm 'liith the fort-going and other objects in view, my invention consists in certain novel features oi ronstriwtioo and arrangement of parts, lu'rviuui'tet' more lully described,

claimed and illustraloiiin the accompany- S i'iig drawings, in pinch v ",'=1 1gure,l is a side olctutional \lOW of a machine of my improved construction with 13, the latter being fixed to and depending from said table. roller i4 is mounted {or rotary movement above the table 10, said roller being adapted to initially spread the pour 15 of molten glass into sheet form as designated by 16. Arranged at it suitable point above the table 10 is a shaft ii on which is loosely mounted a series of bobbins 18, each containing a strand of wire of appropriate gage. By thus mounting the bobbins loosely on the shaft 17 they may be readily shifted; lengthwise on said shaft. properly spaced apart, or readily renniyed, thus permitting the introduction of various sizes of bobbins according to the length of wire required.

The wires from all the bobbins feed between the teeth i9 o a comb 20, the same being in ated adjacent to the Series of bobbins and the th nt' said comb are relaiyely c oset t ether than the bobbins so that tlu NlIUH converge from the bobbins t0- 'Wllltl tin; comb and from the latter said wires pass in parallel lines downward to the point where they arev embedded in the glass. Said wires pass between the teeth 21 of a senoud comb :2, the latter being, located adjacent. to roller i i and being for the purpose of holding: the wires properly spaced apart. Imumiiately adjacent to this comb 39 is an idle roller 23 beneath which the wires pass and from thence said wires pass through a slotted guide 24, the same being located slightly shove the surface of table i An embedding roller is mounted for rotation in suitable hearings ata point adjacent to the slotted guide :54, the surface of which embedding roller is preferably smooth and as the table 10 moves toward the left hand, this roller embeds the strands of wire in the top surface of the sheet; of glass 16.

An initial spreuding A finishing roller 26 is mounted in suitable bearings above the table 10 which finishing roller is for the purpose of spreading the second pour 27 of molten glass in sheet form over the sheet 16 and the strands of wire embedded therein, thus producing the completed sheet of glass 28.

A suitable clamping device 29 is positioned on the forward end of the table, which. device is adapted to firmly grip the ends of all of the strands of wire.

In operation, the table 10 is moved toward the right hand until its forward end is positioned beneath roller 14. The first pour 15 of molten glass is now dumped onto said table to the rear of roller 14 and the table is now advanced until the ends of the wires are in position to be engaged by the clamping device 29. After the ends of the Wires have been gripped by said device, the table is further advanced and during such movement the wire from the bobbins pass downward between the teeth of combs 20 and 22, beneath idle roller 23, through slotted guide 24, and beneath roller 25 which embeds the strands of wire in the top of the sheet of glass 16 formed from the-first pour. The table is further advanced and the second pour of molten glass is dumped onto the first sheet 16 immediately to the rear of roller 26 and as said. table continues to advance the second sheet 28 is formed immediately on top of the first sheet 16 with the single strands of wire? embedded between the two sheets. The table is moved forward until both pours of glass are spread, thus completing the finished sheet, and after the wires have been severed at the rear end of said sheet, the latter is removed from the table and annealed in the usual manner.

When the ends of the strands of wire are engaged by the clamp 29 at the forward end of the table, it will be understood that said clamp occupies a position immediately adjacent to roller 25 and for this reason very little wire is lost or projects from the forward end of the completed sheet.

The two sets of combs and the idle roller the centers of the slots in the bar 24 and this prevents the splices in the Wires from catching and interfering with the free operation of the device.

When the sheet is finished the wires are cut off immediatedy ahead of embedding roller 25, leaving projecting ends of sulficient length at the rear end of the completed sheet, and likewise leaving ends of suflicient length in front of the slotted bar 24 so that the ends of the wires will not spring backwardly through said bar.

The combs 20 and 22 together with idle roller 23 form tensioning means to regulate and control the movement of the strands of wire in their passage from the bobbins .18

to the point where they are embedded in the first sheet 16, and as the bobbins are independently mounted on the shaft 17 it is not necessary to provide independent tensioning means for the various strands of wire.

It will be readily understood that minor changes in the size, form and construction of the various parts of my improved device can be made and substituted for those herein shown and described, without departing from the spirit of my invention, the scope of which is set forth in the appended claims.

I claim:
